Design Engineer, James Greenberg was quoted in a recent story that appeared in Electronics for Engineers saying, “The Micro Harmonics isolators have a really wide band which allows us to look at a range of molecules at different frequencies using the same spectrometer as previous experiment with the exact same isolator.” Read the full story [...]
Radiation Testing of Micro Harmonics Isolators Space exploration has always pushed the boundaries of technology, requiring instruments that can withstand the harsh conditions beyond Earth’s atmosphere. One of the critical factors that must be considered when designing space-based instruments, such as isolators, is their ability to endure the effects of radiation, particularly the Total Ionizing [...]
System designers are overcoming the issue of signal reflections at MMW and THz frequencies. “High isolation was extremely important, and we were getting 30 dB of isolation with the isolators from Micro Harmonics at over 300 GHz,” explains Research Scientist James Greenberg.

Multipaction Analysis for Millimeter-Wave Isolators and Hybrid Circulators Multipaction [1, 2] is a phenomenon occurring primarily in RF systems operating in a vacuum such as those found on space-based platforms. RF fields accelerate charged particles (electrons) which gain energy and collide with surfaces. If the impact energy is sufficient, additional electrons are released from the [...]

Within the terahertz technology gap lies a vast reserve of bandwidth poised for development. However, creating user-friendly technologies capable of generating, manipulating, and detecting radiation within these frequency bands is not only technically challenging but has also been hindered by the limitations of available THz-capable components. That is until we developed our MMW isolators. Read [...]
VDI manufactures extenders for new, compact USB VNAs. The company can extend the test and measurement capabilities up to the lower end of the THz regime (400 GHz) bridging the gap between low cost and high performance. The enabling technology for VDI is our patent-pending millimeter wave hybrid circulator (150 to 190 GHz). Read the [...]
Recently, researchers at IMRA – a creative research and innovation organization that develops essential technologies for industrial use – overcame many of the issues associated with the THz regime when working at frequencies above 300 GHz. In a recent article from eeDesignIt, they detail how our millimeter wave isolators helped advance the research in the [...]
Why Are Y-Junction Circulators Difficult to Find Above 100 GHz Y-junction circulators are used to direct signal flow in millimeter-wave (MMW) transmit and receive systems. At the heart of the device is a ferrite core located at the junction of three waveguides. The magnetically biased ferrite is non-reciprocal which gives rise to the unique circulator [...]
The scientific community is striving to bring life to the so-called “dead zone”, a region of the electromagnetic (EM) spectrum between electronics and optics. This band, often referred to as the “terahertz gap”, resides between 100 GHz and 30 THz. EverythingRF recently published an article mentioning how our isolators are helping bridge the gap.
